Abstract
Controllable operation between different magnetic topological states, such as skyrmions and bimerons, which share the same topological charge but exhibit distinct properties, has garnered extensive attention due to their potential applications in future high-density memory technologies. However, their remarkable origin mechanisms (e.g., in-plane and out-of-plane easy magnetic axis) make effective control of their switching a huge challenge. Based on first-principles calculations, we explore the 2D RuClBr/Ga2S3 van der Waals heterostructure and find that the skyrmion and bimeron topological states could be switched instantaneously and efficiently by regulating the electric polarization of Ga2S3 with an external electric field. Additionally, atomic spin dynamic simulations reveal that the evolved skyrmion and bimeron magnetic configurations are highly resistant to external disturbances, enduring external magnetic fields of up to 20 T. This efficient transformation between magnetic states is driven by magnetic anisotropy accompanying changes in the polarization state. Our work predicts that the RuClBr/Ga2S3 system is an ideal platform for addressing this control problem.
期刊介绍：
Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology.
In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics.
APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field.
Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
